Answer :
Everything inside of the parenthesis needs to be to the 4th root. So you can see it as:
3^4 * (b^3)^4
3^4 = 3*3*3*3 = 81
And using rules of exponents, you need to multiply those exponents.
b ^ (3*4) = b^12
Put them together... 81 b^12
3^4 * (b^3)^4
3^4 = 3*3*3*3 = 81
And using rules of exponents, you need to multiply those exponents.
b ^ (3*4) = b^12
Put them together... 81 b^12
